Title: Improvements in mechanical bearings for rotary shafts
IPC: F16C27/02
Filed: 1931-12-19
Abstract: 394,010. Cylindrical journal bearings; lubricating. GRAY, P. W., c/o Sperry Gyroscope Co., Great West Road, Brentford, Middlesex.-(Sperry Gyroscope Co., Inc.; Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.) Dec. 19, 1931, No. 35202. [Classes 12 (i) and 12 (ii).] A bearing for vertical shafts particularly of the rotors of gyroscopic ship stabilizers, turbine rotors, generators, and the like, has in addition to the main bearing part 11 auxiliary bearing blocks 22 with less clearance between said blocks and the rotor shaft than in the main bearings, the blocks having yielding means to permit them to retreat to the surface of the main bearing under more than a predetermined load. The bearing shell 11 is supported universally in the housing 12 and has a row of blocks 22 preferably square and of small area spaced near the centre in clearance holes. The sides of the blocks are slightly curved, and at the back, where each block is engaged by a spring-urged base 28, it is slightly bevelled to assist in the building-up of an oil film at the bearing surface. Lubricant is supplied through a port 36 to the blocks 22, and the branches 38, 39 lead to grooves 391 in the main bearing 11. The main bearing is preferably of the type described in Specification 193,381, [Class 12 (i), Bearings &c.], in which the bearing lining is in four arcs, and an auxiliary bearing block 22 is preferably located in the centre of each arc. In a modification, the pressure is transmitted by a spring 261, Fig. 5, to each block 22 <11> through a piston 45 and abutments 49, 52. Hydraulic pressure is led through a passage 47 to the back of the piston 45 when starting up to relieve the blocks from load. To ensure a good connection between the babbit, lining 13 and the main bearing shell 11, Fig. 7, the babbitt is cast in the shell and when it is cool it is subjected to hydraulic pressure beyond the yield point. This is done by clamping plates 15, 16, and packing 18, to the ends of the shell 11 by bolts 17 and by admitting pressure fluid into the bearing interior through a pipe 20. The Provisional Specification describes an arrangement wherein the auxiliary bearing blocks are pressed towards the supported shaft by hydraulic pressure instead of by springs.

Abstract: 448,862. Prepayment mechanism for meters. WILSON GASMETERS, Ltd., G., Foleshill Road, Coventry, WILSON, J. H., The Mill House, Baginton, near Coventry, and ORMEROD, G. A., 24, Ash Tree Avenue, Coventry. Dec. 10, 1934, No. 35387. [Class 27] In a multi-coin prepayment mechanism for gas &c. meters having coin-controlled driving wheels connected through change-speed gearing to the quantity-mechanism so that the drive is dependent on the value of the coin inserted, the driving wheels and gearing are both arranged within the casing enclosing the coin-pocket mechanism. When a penny or shilling is inserted through a slot 10 in a face plate 11, Fig. 1, a slide 13 is depressed and a tooth 14 is engaged either with a " penny " wheel 16 or with a " shilling " wheel 15. At the same time the coin connects a slotted disc 17 rotatable by a knob 18 with the slide. The change-speed gearing is as described in Specification 448,868. It comprises a planetary gearing of which the " coin " wheel that is being rotated is the driving element, the other " coin " wheel being held by a pawl 19 as the reaction element. The driven element of the gearing 20 carrying the wheel 21 includes the planet carrier 22 which encloses the double planet-wheel 23, the externally - toothed sun - wheel 24 and the internally-toothed annulus 25, the wheel 24 and annulus 25 being fast respectively with the wheels 16, 15. The gearing is thus sealed and can run in an oil bath. The wheels 15, 16 and the gearing 22 ... 25 are arranged within the casing 12 of the coin-pocket mechanism. In the form shown in Fig. 2, where the toothed annulus 26 is the driven member, this is carried by a casing 27 which encloses the double planet wheel 28 and the internally-toothed annulus 29.

Abstract: 804,364. Rotary engines. McCLOSKEY, J. March 1, 1956 [Dec. 13, 1954], No. 35956/54. Class 110 (2). [Also in Group XXIX] Liquid under an hydrostatic head passes from one end of a pipe 2, via a passage 16 in a block 6 on the pipe 2 and a radial pipe 9, to the upper one 11 of two tanks rotatable with a tube 7 around the block and, as the tank 11 fills, the displaced air, passing via a pipe 13 into the previously filled lower tank 12, forces the liquid therefrom via pipe 10 and passage 17 and out of the other end of the pipe 2, so that the now heavier tank 11 descends, rotating the whole tank assembly about the pipe 2. The displaced liquid is ejected through spraying apertures 5 and the apparatus, mounted on wheels 3, 4, progresses along an elongate closed circuit rail 1 by virtue of the wheel 4 being fixed to the tube 7. To ensure unidirectional rotation, the apparatus is so arranged that the angle between the axis of the upper tank and the horizontal (measured in the desired direction of rotation) is less than 90 degrees. For this purpose, each tank may have a projecting rod 24 which depresses a spring-loaded catch 25, to pass it in the desired direction and to come to rest against it as the tank swings back. The catch may carry a magnet 27. Three tanks spaced at 120 degrees may replace the two diametrically opposed tanks, the individual air pipes being interconnected at a central point. The apparatus is so balanced that, when turning around each end of the circuit, it can travel on its driving wheel only. Additional air, to maintain the supply, may be introduced to the system by a pump operated by the reverse swing of the tanks in coming to rest, or may be entrained by running the supply outside the hydraulic gradient. It may be used for irrigation, the supply of nutrient solution, or to dirve any other device. The pipe 2 may be arranged to rotate about a fixed vertical axis, the wheel 4 running on the ground.

Abstract: 367,911. Recording sound ; television receivers. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A., and KEITH, C. R., 4, Arcade House, Finchley Road, London. Nov. 29, 1930, No. 36011. [Class 40 (ii).] In apparatus wherein a light beam is controlled by an optical valve or shutter operated in response to oscillating or varying phenomena, as for example in sound recording, television, &c., a diffusely reflecting body such as ivorine, white paper, &c., is disposed to intercept part of the light issuing from the valve and deflect it to the eye of an operator whereby he may observe changes in the average amount of light over short periods of time and thus detect incorrect normal setting or overloading of the valve. As shown, a valve 3, Fig. 1, operating on the principle of the Einthoven string galvanometer comprises a ribbon bent into parallel limbs and arranged between the poles of a magnet apertured for the passage of a light beam from a source 1 directed by lens systems 2, 4 to a sensitized surface 5. A diffusely deflecting surface 7 may be introduced into a part of the path of the beam to deflect a part of the light through a viewing aperture 8. As shown in Fig. 2, an ivorine reflecting surface 9 is mounted by a bent spring 10, Fig. 4, within a tube 11 mounted on the magnet yoke 17 and engaging over the tube 18 housing the lens system 4. By means of an adjusting screw the surface 9 may be advanced into the path of the beam to reflect a part through a gap in the tube 11, which gap may be covered with a transparent window. The method is also applicable in association with light valves of the Kerr cell and oscillograph type.
